Default Outside temp reading is wrong

The outside temp reading in my GX is not accurate, it's showing 70-75 when its 91 outside. What do I need to do? Just replace this sensor? http://www.rockauto.com/m/mobilecata...rttype=7000&ck

I'm thinking the ACDELCO at the bottom of list?

I would first remove the sensor, clean it thoroughly, clean the connections, put dielectric grease in the pigtail and reinstall. Consider where the sensor is located, constantly exposed to the elements and road grime, it's pretty abused. That fixed one on a Jeep ZJ I had a while back. Might save you some cash if it works.

I agree. Unplug it, clean it, inspect for corrosion, plug it back in.

I think I saw it behind the front bumper, right below the fan, dead center.

I'm sorry, told you wrong. It's located dead center of the grill opening area between the aux fan and the horn assembly.
